Triacontanol is a growth stimulant for many plants, most notably roses, in which it rapidly increases the number of basal breaks.

[4] The effects of triacontanol may also be seen when a chopped[clarification needed] alfafa plant is placed in close proximity to the seedlings and various crop seeds.[which?]

A substantial increase in yield and growth has been seen in different plants, such as cucumber, tomatoes, wheat, maize, lettuce, and rice.

In tomato plant (C-3 plant), the treatment of triacontanol increases the dry leaf weight and inhibited the photosynthesis by 27% in dry leaves,{{Eriksen AB, Selldén G, Skogen D, Nilsen S. Comparative analyses of the effect of triacontanol on photosynthesis, photorespiration and growth of tomato (C3-plant) and maize (C 4-plant).

[citation needed] Triacontanol improves the rate of cell division in a plant that produces larger roots and shoots.

[citation needed] When photosynthesis operates efficiently, the plant produce more sugars and absorb more sunlight.

The plant then send more sugars to the rhizosphere via the root system where the growth, respiration and nutrient exchange take place in the vicinity of the soil.

[10] Availability of more sugars lead to more respiration and nutrient exchange between the plants and the microorganisms in the soil.

when the microbes receive more sugars from the plant, it increases the microbial activity in the root zone and they perform more efficiently in mining the nutrients like in the case of nitrogen fixation.

Overall, despite other benefits from adequate amounts of triacontanol, the effect of enhanced photosynthesis may increase the plant outcomes.

[12] Cocoa seedlings (Theobroma cacao L.) shows a positive growth in terms of plant length and the leaf size when treated with triacontanol.

In the hypocotyl treatment of triacontanol in the mangrove plant resulted in increased root and shoot growth.

Similar effects of triacontanol can be seen with a variety of plants like rice, wheat, corn, maize, cucumber, and many more.
